In this review, published in Cell Host & Microbe, it’s described the recent progress in understanding of both type I and type III IFN-mediated innate antiviral responses against human coronaviruses and discussed the potential use of IFNs as a treatment strategy for COVID-19. Type I and type III IFNs establish the cellular state of viral
Molecular mimicry is an evolutionary strategy adopted by viruses to exploit the host cellular machinery. This paper reports that SARS-CoV-2 has evolved a unique S1/S2 cleavage site, absent in any previous coronavirus sequenced, resulting in striking mimicry of an identical FURIN-cleavable peptide on the human epithelial sodium channel α-subunit (ENaC-α). Genetic alteration of ENaC-α causes
In a recent Comment published on EBioMedicine entitled “COVID-19 as a STING disorder with delayed oversecretion of Interferon-beta”, Berthelot and Lioté suggests that SARS-CoV-2 firstly inhibits interferon release but the NETs self-DNA induces delayed activation of STING with“cytokine storm”, causing the combination of interstitial lung disease and inflammatory vasculopathy. The assumption that SARS-CoV-2 had no
In this new paper, published on medXriv https://doi.org/10.1101/2020.05.20.2010223 the outcomes of thirty-nine hospitalized patients with severe to life-threatening COVID-19 who received convalescent plasma transfusion were compared against a cohort of retrospectively matched controls. Plasma recipients were selected based on supplemental oxygen needs at the time of enrollment and the time elapsed since the onset of
In a paper just published on Preprints, REGENHEALTHSOLUTIONS Research Team shows that, in Covid-19 critically ill patients, serine proteases released by recruited neutrophils are responsible for endothelitis, NETosis, platelet activation, ULVWF multimers release, thrombi formation and MOF for viral sepsis. Based on Chinese CDCP report on COVID-19, 14% of patients presented severe disease and 5%
There has been a surge in cases of an inflammatory syndrome in children, believed to be linked to covid-19, following an alert to doctors in the UK at the end of April. The syndrome, which in the UK is referred to as the “paediatric inflammatory multisystem syndrome which is temporarily associated with SARS-CoV-2,” has also
The Smithsonian Science Education Center, in collaboration with the World Health Organization (WHO) and the InterAcademy Partnership (IAP)—a partnership of 140 national academies of science, engineering and medicine—has developed “COVID-19! How can I protect myself and others?,” a new rapid-response guide for youth ages 8–17. The guide, which is based on the UN Sustainable Development Goals,
With a discovery that could rewrite the immunology textbooks, an international group of scientists, including the teams of Bart Lambrecht, Martin Guilliams, Hamida Hammad, and Charlotte Scott (all from the VIB-UGent Center for Inflammation Research) identified a new type of antigen-presenting immune cell. These cells, that are part of an expanding family of dendritic cells,
Antibodies from blood donated by people who recovered from the illness and hyper-immunoglobulins are becoming treatments of choice for COVID-19, with recombinant polyclonal antibody approaches to follow. A group of US academic researchers has sparked a nationwide effort to encourage people who have recovered from COVID-19 to donate plasma, which will be used to treat patients across
MIT Study finds specific cells in the lungs, nasal passages, and intestines that are more susceptible to infection Researchers at MIT; the Ragon Institute of MGH, MIT and Harvard; and the Broad Institute of MIT and Harvard; along with colleagues from around the world have identified specific types of cells that appear to be targets
